What should you know about excessive wind and bloating?

Gas can build up when air is swallowed while eating quickly, chewing gum or drinking fizzy drinks. Gut bacteria also ferment some carbohydrates, producing wind and a stretched or full sensation. Constipation can trap gas, while irritable bowel syndrome may link bloating with abdominal discomfort and changes in stool pattern.

Food intolerance, including lactose intolerance, can cause symptoms after particular foods. Coeliac disease may affect digestion after gluten exposure and requires proper testing rather than self-diagnosis. Giardiasis can follow contaminated water or food and may cause prolonged diarrhoea. Helicobacter pylori infection can be associated with upper-abdominal symptoms.

Eat slowly, chew thoroughly and consider smaller meals. Reduce fizzy drinks, chewing gum and habits that make you swallow air. Gentle walking can encourage bowel movement; drinking enough fluid and gradually increasing fibre may help constipation, but a sudden large fibre increase can worsen gas.

Keep a short food-and-symptom diary, recording meals, stool changes and timing. Avoid removing several food groups without guidance, because this can make nutrition harder and obscure the trigger. Nutrition counselling can help plan a balanced elimination and reintroduction approach when symptoms keep recurring.

Seek urgent care for severe or rapidly worsening abdominal pain, a swollen hard abdomen, repeated vomiting, inability to pass stool or gas, blood in stool, fainting or breathing difficulty. These signs can indicate a problem needing prompt examination.

Arrange a medical review for persistent bloating, unexplained weight change, ongoing diarrhoea, constipation that does not improve, fever, anaemia symptoms or symptoms that repeatedly wake you. A clinician may assess the abdomen and choose targeted tests based on the pattern.

Ask whether constipation, intolerance, IBS or another digestive condition fits your symptoms, which tests are appropriate, and how to change your diet without losing key nutrients. Bring your symptom diary and list of medicines or supplements.
